Anti-KRT4 Antibody

Supplied by Antibodies.com, this primary antibody is a Rabbit polyclonal reagent raised against the cytokeratin 4 target (KRT4) and is offered in a 50 µL format at 1 mg/mL. The immunogen is a recombinant protein of human KRT4, and the antibody was purified by affinity purification using the immunogen, ensuring selective recognition of the endogenous target. It is supplied unconjugated in phosphate buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4, with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as stabilizers, and should be stored at –20 °C to preserve activity. Validated applications include Western blot (WB) and immunohistochemistry (IHC), as demonstrated by the supplier's own Western blot analysis of mouse liver cell line extracts and IHC staining data shown on the product page. The antibody has been characterized for cross-species reactivity with Human, Mouse, and Rat samples, making it suitable for a broad range of cell and tissue-based research workflows. As a polyclonal reagent, it contains a diverse population of immunoglobulin molecules directed against multiple epitopes of KRT4, which is advantageous for detecting low-abundance targets and for tolerance of minor antigen variations. The product is dispatched from Stockholm with a typical lead time of 5–8 business days and is intended for research use only, not for diagnostic or therapeutic applications. Researchers working on epithelial differentiation, oral and esophageal keratinization, or cytokeratin expression profiling will find this antibody a reliable tool for routine immunoblotting and tissue-section studies across the three listed species.
